Perfection, Being Worked Out

Question, regarding the following scripture, how do you see Him Christ Jesus being formed within you?

There are those that either see themselves having no soul, or that in the rebirthing along with their spirit being made perfect, their soul likewise was made perfect.
I'm sure there are many other ideas floating around as well.
Somehow because of the unseen details of our soul/spirit, talking about such matters seems none relevant to knowing Him?

Galatians 4:19 My little children, for whom I am again suffering birth pangs until Christ is completely and permanently formed (molded) within you...

I look forward to any thoughts the Father is making known to you!!!
